You can see photographs of all the samples displayed in a periodic table format: my pictures or their pictures. Or you can see both side-by-side with bigger pictures in numerical order. The picture on the left was taken by me. Here is the company's version (there is some variation ...
All LTS releases will be assigned a "codename" drawn from the names of elements on the Periodic Table of Elements. For each upcoming LTS release, the Release working group will select a handful of candidate names and submit those for a collaborator vote. I looked up the List of chemical el...
